Seagate released the Guardian Series in mid-2016 with a focus on high performance, capacity, and reliability. Seagate designed its flagship desktop HDD for creative professionals, enthusiasts, and gamers. It features a speedy 7,200-RPM design with up to 10TB of capacity and an advanced cache system.

Most of us have transitioned to flash for our boot drives, but HDDs still serve a vital role for capacity storage. SSDs became more affordable in the same time frame as the catastrophic 2011 Thailand floods that crippled the bulk of global HDD manufacturing capacity. The flood washed away the final assembly factories and also the third-party factories that supplied components to the leading HDD vendors. As a result, hard drive prices increased while more powerful SSDs began a steady price decline that would continue for the next five years. As the HDD industry recovered, the vendors slashed warranties and focused on commoditized products.

Call it karma or whatever you will, but we have come full circle. SSD quality has declined as the flash industry enters its own commoditization phase and pricing has increased due to component shortages. Once again, we are looking for alternatives.

Hard drives can't compete with SSDs on the performance front. Even SSHDs (Solid State Hybrid Drives), which are much faster than normal hard drives due to a small amount of onboard flash, have failed to bridge the gap. Those products use low-cost, low-performance controllers to manage the flash, but that results in very inconsistent performance.

Intel's new Optane Memory smooths the consistency issues we usually encounter with HDD caching technology. Intel's Optane moves beyond flash with new 3D XPoint memory that is faster and more reliable than flash, but it's also expensive. You also need a motherboard made in the last year that supports the memory, and for many users that upgrade requires a new processor and DDR4 memory. Optane Memory will not enjoy significant uptake until newer chipsets become more prevalent.

The HDD vendors are not waiting for Optane Memory to improve their products. The Seagate BarraCuda Pro borrows advanced caching technology from the company's own enterprise line to increase performance. The drive also uses Helium inside the casing to reduce friction, which has the side effect of offering increased reliability and capacity.

The Seagate BarraCuda Pro comes to market in five capacities that range from 2TB to 10TB. All five 7,200-RPM models offer 220 MB/s of sequential throughput and 4.16ms of average latency. Those are the only performance specifications listed.

Seagate says that the BarraCuda Pro leads the industry in random read and write performance, but it doesn't disclose any detailed data. HDDs are magnitudes of order slower than flash-based devices during random workloads, which is why they are slower than SSDs in desktop applications. We can understand why Seagate doesn't want to publish random performance data, which is orders of magnitudes less than even the slowest SSDs, but if a company claims to be the "best" in a category, it should back it up with detailed specifications.

The BarraCuda Pro series ships in a standard 3.5" form factor with a 6Gb/s SATA interface. HDDs are complicated precision instruments inside the case, but they are simple for end users. Windows automatically manages the data through disk defragmentation schedules, and the advanced cache algorithms automatically boost performance.

Seagate Multi-Tier Caching Technology

All hard drives in the BarraCuda family come equipped with Seagate's Multi-Tier Caching Technology (MTC). This technology boosts HDD performance by applying intelligent layers of NAND, DRAM, or media cache. Each class of drive employs different features of the MTC suite, so our drive doesn't use a NAND component. The BarraCuda drives deliver improved read and write performance by optimizing the data flow through the various layers of memory-based cache.

The BarraCuda Pro uses an Avago drive controller. Avago purchased several storage-focused companies over the last few years, including LSI (that included SandForce assets), Broadcom, PLX, and others. Many of these companies hold IP in advanced caching technologies that Seagate uses to increase performance.

Hard drives use an address translation layer similar to solid-state drives. Over the last decade, and increasingly over the last five years, the technology has improved. For instance, the fastest section of the platter no longer holds data for long term storage. Now Seagate uses that section of the platter an extension of the cache hierarchy; it holds a copy of the data resident in the volatile SRAM and DRAM caches. That allows the drive to safely cache user data in the volatile memory, which in turn can be used more effectively to boost performance. Seagate calls the sliver of high-speed disk the Media Cache.

Pricing, Warranty & Endurance

The Seagate BarraCuda Pro 2TB sells for $129.99 and pricing scales with capacity. The 10TB model we're testing retails for $399. You pay more for increased capacity, but many of the other specifications remain unchanged. For instance, every drive in this series features the same performance and endurance specification.

Hard disk drives have their own unique endurance measurements. The drive tolerates 300,000 load cycles, which is a measurement of how many times the drive arm moves on and off the ramp that secures the arm when the drive powers down. The workload rating is 300TB per year, which works out to 1.5 petabytes over the five-year warranty. We would call this a 1.5 PBW (Petabytes Written) rating if this were a consumer SSD.

The warranty also includes two years of Seagate Rescue Data Recovery Service. Seagate tells us the service has a 90% success rate and covers mechanical failures, accidents, and natural disasters.

We've covered data recovery services in the past and learned that this type of service isn't cheap. A 2TB HDD recovery can cost nearly $1,000 through a third-party service. Seagate doesn't provide users this service throughout the full five-year warranty, but it does provide two years of extra replacement coverage should something happen to your drive.

The BarraCuda Pro doesn't have a painted external case. I was reluctant to put a magnet on the case to see if it's aluminum or steel, but it looks quite different in bare metal form.

The Seagate BarraCuda Pro 10TB uses more platters than consumer HDDs did a decade ago, and each platter experiences air resistance and causes air turbulence inside the drive. Helium is lighter than the air we breathe, which reduces resistance and turbulence.

The BarraCuda's PCB is a standard affair with a drive controller, motor controller, and two RV sensors on opposing corners. The RV sensors allow the drive to detect and counteract vibrations.

... what's a "NAND duffer"? I guess it doesn't matter since it has none. <grin>

Someone gonna fix the typo in the summary/verdict box?

Where's the 20tb??

A NAND buffer.

What about noise please? That is basically my only parameter, along with size.

I see WD Green at high prices. My last 1terrabyte drive was Canadian $49.00. Obviously a deal.However I should not be paying more than $60/terrabyte. for up to 2 terrabytes, and then lower cost per terrabyte for the additional terrabytes. Note the 3TB model at $102.00

I went through 6 Seagate 2tb drives in the past couple of years. Even though I bought brand new in the box disks they would only send refurbished replacements and *every single one of them* died within six months. Had to reinstall my OS multiple times and lost a fair share of files. Seagate used to be *the* brand to trust for reliability but now I wouldn't take one for free, the last two dead drives are still sitting on my shelf still under warranty and I don't even want the replacements.

I have had two WD drives fail from the same shipment. I got both replaced with new ones from WD and no more problems with them since. I now put that down to rough treatment in transit. It still seems strange that parked heads still seem to cause some sort of damage in transit. Is there a maximum G force for parked heads?

Saying it's not entirely Seagate's fault is wrong. It is entirely their fault.You forgot to mention Seagate had and still has designing flaws on their hardware, going from platters all the way to bad firmware. Their customer service is also a nightmare, they keep sending refurbished drives that will fail in only a few weeks of use. Once you buy a seagate drive, don't expect that much from that company. I will never buy a product from them ever again, whether it is consumer or enterprise level.

The barracuda pro comes in 12TB, I bought one today (!)

Do Seagate drives still run hot enough to cook on? I've never yet had a HDD fail--and I've never owned any Seagate drives. Coincidence? Doubtful.

I agree, do some sound readings. Of course, the amount of noise a 10TB drive makes is not likely to be representative of the noise produced by the capacities people actually use. Why is a 10TB drive being tested anyway? Sure, a small minority of people use these ultra-high capacity drives for things like bulk video storage, but it's not really representative of what most people use. Even most of the higher-end gaming builds you see listed at this site only include a 1TB hard drive, despite the 2TB capacities only costing a little more. Most people don't feel they need that much storage. Reviewing high capacity drives is fine, but such reviews won't necessarily be all that relevant to the people putting lower capacity drives in their systems. Reviews for drives with capacities in the 1TB to 4TB range would undoubtedly be more relevant. For the most part, outside of some server applications, these high capacity drives are mainly just used for bulk-storage and backups, so their performance isn't as important anyway.

Also, how many platters are these drives? The number of platters tends to impact reliability and noise, along with performance if the density varies between models, so it can be relevant information to know. Checking around, it appears to be a 7-platter drive, but how about the lower capacities? Is the 2TB a 2-platter and the 4TB a 3-platter design? If so, will that affect their performance?

Quote:

Seagate gained a bad reputation for disk failures over the last few years, but the failures weren't entirely Seagate's fault. For many years large retailers shipped drives in substandard packaging. It was common to wrap a drive with bubble wrap and toss it into an oversized box. A large and vocal web hosting company also removed commodity desktop drives from external enclosures and used them in poorly-designed servers. The company also subjected the drives to workloads they weren't designed for and published failure rate data. Seagate has addressed many of those issues and is working on a full image makeover.

Sure, the treatment of the drives during shipping can potentially affect reliability, and a web hosting company using consumer drives might not be entirely representative of their reliability in a home system, but ultimately that should affect drives from all manufacturers, not just Seagate. If Seagate has more failures than the competition under the same conditions, then that's still arguably their fault.

This is an enterprise-targeted drive. It has vibration sensors and compensation, for heaven's sake. I wouldn't buy one for home use; if I were building out a large storage server with an HDD layer I would need the high-density storage, resistance to the vibration problems caused by many HDDs spinning the the same frame, and guarantee of data recovery (not so big a deal, I'd be using some level of RAID).

As a consumer, the first thing that I see is that this is overpriced for me.

sstanic

It is not an enterprise-targeted drive. I don't base my decisions on what other people buy. Overpriced is relative. Still no noise numbers, such a conspicuous omission..
